To all whom it may concern. I

Be it known that I, GUSTAVE CooK, a citizen of the United States, and a resident of Gillett, in the county of Oconto and State of Wisconsin, have invented certain new and .useful Improvements in Headlights, of

which the following is a specification.

Myinvention relates to improvements in headlights for vehicles, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of the invention is the provision of simple and efficient means for supporting headlights of an automobile so that such headlights will turn withthe steering wheels of the automobile and rays of light therefrom will be projected directly inadvance of the automobile, irrespective of whether or not the automobile is proceeding along a straight path or is turning a corner. A further object-of the invention isthe provision of a means for supporting a headlight and for attaching the headlight to the steering mechanism of an automobile without any change being required in the usual construction of the steering mechanism. a

A still further object of the invention is the provision of an improved means for sup orting the headlight of an automobile so t at motion will be transmitted thereto from the steering mechanism of the auto-' mobile Without any appreciable friction or noise resulting from the operation of the headlight supporting means.

Other objects and advantages of the in vention will be apparent from the follow ing description, considered in conjunction with the accompanying drawings, in which Figure 1 is a fragmentary perspective view, showing the headlights of an ,auto-' mobile supported and connected with the steering mechanism of the automobile by means embodying the invention, [j j a a Figure 2 is a relativelyenlarged 'view, partly in side elevation and partly in vertical section, showing the supporting and op erating elements for one of the headlights,

Figure 3 is a section along the line- 3+3 of Figure 2'and, c

Figure 4 1S'& fragmentary side elevatlon of a portlon of the transverse connectmg rod of the usual steering mechanism and the elements which the invention provides for attaching the supporting and operating means for one of the headlights to the cross connecting rod.

In Figure 1 I show more or less diagrammatically the front end portion of an automobile, indicated. generally at 1. A cross connecting rod 2 provides the usual means for transmitting motion from one of the steering arms, snch as that indicated atS to the other steering arm, not shown, so that the front or steering wheels of the automos bile will. turn in unison when the connect ing rod 2 ismoved axially Motionlto effect steering of the automobile may be imparte edto, the connecting :rod2 by any suitable known means under the control of-thedriver of the automobile, no means belngshown n the drawings. Y

The parts described so far; are ordinary in construction and form no part of the invention except in so faras they cooperate with? the parts which will now be described.

A pair of headlights 4 is provided for the automobile. ,Each of these headlights is supported and connected by means embodymg the inventionto the connecting rod 2 so that the headlight will turn about a vertical axis as the steering wheels of the automobile are turned and in the same direction as the steering wheels'so that the headlights will project rays of light directly in front of the automobile, irrespective of the direction of movement of the automobile. The means for supporting one of the headlights 4 for actuation by the connecting rod 2 is precisely identical with the means for supporting the other headlight for actuation by the same connecting rod and I therefore shall confine my description to the supporting and operating means for one headlight, it being understood that the supporting and operating means for the other headlight comprises at identical parts. a

The jheadlight casing is carried between a. pair of alined; horizontal pins, as at 5, which extendithrough alined openings in the upper-end portions of the upstandingforks-6 ofa lampsupporting yokes 7. The yoke 7 has a .base8 which is formed with a central recess 9 in its bottom The recess 9 is preferably circular in cross-section"'aii'd receives the enlarged upper end portion of a tubular standard 10. The standard. 10

. has a reduced lower end portion 11 dependfronting faces thereof.

be interposed between the shoulder 15 at the upper end of the reduced lower end portion 11 and the supporting fender- 13.

A similar washer 16 maybe-disposed 911'. 1 1.

reduced lower end portion 11 between the lower face of the fender 13 and a clamp.- ing nut 17 which is in threaded engagement with the reduced lower end portion 11 of thetubularstandard.

The base 8* of he yoke and'the upper end of the tubular standard 10v haveannular grooves 18' a-nd'19, respectively, in the coni I These grooves 18 and 19 cooperatetoaform a runway or race for ball bearings 20 which anti-frlctionally support the yoke "Z on the, tubular standard lllfor rotation about a vertical @X'IS wh ch extends centrally of the; tubular standarc- 0- 7 me ns-bier nm egfi h yQkQI and therefore the headlight that is 'snpport'ed on the yoke aboutjthefaforesaid vertical axis comprises a, shaft21 which extendsthrough the bore of thetubular standard 10 andlias the upper end portion thereof provided with external screw threads in engagement with. screw threads on thewall of a central socket'22 inthe'base' 8 of the'lamp carrying yoke. Theshaft '21 is rotatable about itslongitudinal axis but 1 is held against any appreciable axial movement upwardby a stop collar-23 which encircles the shaft'21 at the lower end of the tubular standard 10 and is secured tothe shaft 21 by a set screw 24,

The shaft 21 is formed with pair of spaced depending ears or lugs 25 at its lower end provided with alinedhor-izontal openings. Alink 26 for transmitting motion fromthe connecting rod" 2; to the shaft 21- comprises a rod li-ke 'membenha'v-ing one end portion-thereof disposedbetween the depending lugs 25 and ibeing attached. to

the-lugs 25 by a horizontal bolt '27 which extends throughthe alined openings inthe lugs 25' and through anopening in'the portion of the-link 26 which is 'interposed betweenthelngs 25. The otherend portion ofthe linl-26 is enlargedflaterally in opposite-directions for part of its thickness as indicated at 28 and is-'-forined with ajlongitud i-nally extending slotj-29- wh-icl1 'isfe'nlarged in width at its idwer-eridJ-as indicated: at '30. A n'- attachingplate 81 is secured on the connecting rod 2 by clamps 32 or like fastening devicessothat a stud 33 which -is-i ntegral with theattaching plate will be upstanding from the upper part of the connecting rod The stud 3-3 is formed with integral upstanding reduced upper end-portion or pin -projectionfi l and with. apair ofoppositely extending lateral pin projectionsr35; A roller 36 is "disposed onythe;verticalflpin-projection 3.4 which extends through the slot-"29. Rollers 37 are.

slot-:29 for contact with the inner side walls of the slot and the link 26 is held against displacement fromplace on the rollers 37 by a retaining member or cross bar '39 which is in threaded engagement intermediate its ends as at lO with the'threa'ded upper end portion with the vertical pin projection 34 v "From the foregoing description of various parts of the device,theoperation thereof may be readily understood. The tubular standard '10 is'supportedi onithe fender "13 or other stationary part of'the automobile so that the link'26 will extend'obliquely to the direction of length of the connecting rod 2 of'thesteering'mechanism. .It there.- forewill be apparent'that axial movement ofthe connecting rod '2 of the steering mechanism of the automobile will cause rocking of the shaft 21 about a vertical axis, the slotted portion of the llllk'QG' moving relatively to the rollers 36 and'37 and being swung aboutthe axis of the shaft 21 as the connecting rod 2 moves axially. The headlight therefore will be swung or turned about a vertical axis in the same direction as] the steering wheels of the automobile.

The base 8 may beeprovided withan opening 41 inits upper part'leading to the-ball race 1819 and'aiubricant cup 42 may be' arranged with the discharge end thereof secured in said opening.

Obviously, theinvention is susceptible of embodiment in forms other than that which is illustrated in the. accompanyingdrawings and. I therefore consider as my own all such modifications and adaptations thereof asfairl-y fall within the scope of the appended claims.

I claim 1. In adirigible headlight snpportin and operating device, a vertical shaft tatably supported on a stationary part of a vehicle, said vehicle having the usnalaxially movable cross connecting rod between the steering arms for the steering ;-w1 eels of-the vehicle, a plate clamped on saidconnecting rod, said plate having an upstanding stud formed Wltl'l a reducedupper .end portion and-with a pair of oppositely. extendinglateralpin projections,a roller disposed on saidreduced upper end portion of the stud, other-rollers mounted on the lateralpin projections, and a link attached at oneendto the lower end of said shaft and having ajlongi tudinally extending slot in which the roller on the reduced upper end portion of said stud works; theslotted portion of said link restingupon the rollers on sai' d lateral. pin
